Political tensions are rising in the country in the run-up to elections in December, says the BBC World Service Africa editor James Copnall.

Mr Darboe and many of his supporters from the United Democratic Party (UDP) took to the streets in Serrekunda, near the capital, Banjul, on 16 April, demanding the release of their colleague Solo Sandeng "dead or alive".

He had been arrested, along with other activists, two days earlier, and it was alleged that he had died in custody after being beaten.
